The couple got married in 2006 and have two daughters Sunday Rose, 4 and Faith Margaret, 2 and Urban says meeting his life partner was more than just a life changing moment.

"I wouldn't say it was a life-changing moment because it was more than that. It was when my life started. That's the only way I can describe it. Meeting Nic was that profound for me," mirror.co.uk quoted Urban as saying.

Urban, 45, is thankful that Kidman shares a similar ideology with him.

"Before then I didn't really know what I was doing. Now I know exactly what I'm doing and it all makes sense," Urban said.

"I feel very, very fortunate that I've met somebody like Nic and we share the same kind of ideology," he added.
